Mediterranean jellyfish sting-induced Tako-Tsubo cardiomyopathy.

We report a case of a 53-year-old woman swimming in the southern Mediterranean Sea on the Calabrian coast that was suddenly stung on her right forearm by a mauve-pink jellyfish. She got extremely scared and while swimming back to the shore, she accused fatigue and an intense itch sensation. She lost consciousness on the beach as a consequence of a condition of pulseless electrical activity

Regulating working families in the European Union: a history of disjointed strategies

Families in market economies worldwide have long been confronted with the demands of participating in paid work and providing care for their dependent members. The social, economic and political contexts within which families do so differ from country to country but an increasing number of governments are being asked to engage, or better engage, with this important area of public policy. What seems like a relatively simple goal – to enable families to better balance care-giving and paid employment – has raised several difficulties and dilemmas for policy makers which have been approached in different ways. This paper aims to identify and critique the nature and development of the means by which legal engagement with work-family reconciliation has, historically, been framed in the European Union. In doing so, and with reference to specific cohorts of workers, we demonstrate how disjointed the strategies are in relation to working carers and argue that the EU is unlikely to provide the legal framework necessary to bring about effective change in this fundamentally important area of social policy

When is a Partner not a Partner? Conceptualisations of 'family' in EU Free Movement Law

This paper considers the definitions of spouse, civil partner and partner in European Union (EU) free movement of persons law in order to question the EU's heterocentric approach to defining 'family' in this context. It argues that the term 'spouse' should include same-sex married partners in order to ensure that there is no discrimination on the grounds of sexual orientation. It further highlights the problems created by basing free movement rights of civil partners on host state recognition of such partnerships. This approach allows Member States to discriminate on the grounds of sexual orientation and is therefore not compatible with EU equality law in others areas. The position of unmarried or unregistered partners is also considered; in particular, the paper examines the requirement of a duly-attested durable relationship and its impact on same-sex partners wishing to move from one Member State to another. The paper argues that it is time to reconsider the law in this area and bring it in line with the EU's commitment to eliminate discrimination on several grounds, including sexual orientation. © 2011 Taylor and Francis Group, LLC

Carbonic anhydrase activation is associated with worsened pathological remodeling in human ischemic diabetic cardiomyopathy.

BACKGROUND: Diabetes mellitus (DM) has multifactorial detrimental effects on myocardial tissue. Recently, carbonic anhydrases (CAs) have been shown to play a major role in diabetic microangiopathy but their role in the diabetic cardiomyopathy is still unknown. METHODS AND RESULTS: We obtained left ventricular samples from patients with DM type 2 (DM-T2) and nondiabetic (NDM) patients with postinfarct heart failure who were undergoing surgical coronary revascularization. Myocardial levels of CA-I and CA-II were 6- and 11-fold higher, respectively, in DM-T2 versus NDM patients. Elevated CA-I expression was mainly localized in the cardiac interstitium and endothelial cells. CA-I induced by high glucose levels hampers endothelial cell permeability and determines endothelial cell apoptosis in vitro. Accordingly, capillary density was significantly lower in the DM-T2 myocardial samples (mean±SE=2152±146 versus 4545±211/mm(2)). On the other hand, CA-II was mainly upregulated in cardiomyocytes. The latter was associated with sodium-hydrogen exchanger-1 hyperphosphorylation, exaggerated myocyte hypertrophy (cross-sectional area 565±34 versus 412±27 μm(2)), and apoptotic death (830±54 versus 470±34 per 10(6) myocytes) in DM-T2 versus NDM patients. CA-II is activated by high glucose levels and directly induces cardiomyocyte hypertrophy and death in vitro, which are prevented by sodium-hydrogen exchanger-1 inhibition. CA-II was shown to be a direct target for repression by microRNA-23b, which was downregulated in myocardial samples from DM-T2 patients. MicroRNA-23b is regulated by p38 mitogen-activated protein kinase, and it modulates high-glucose CA-II-dependent effects on cardiomyocyte survival in vitro. CONCLUSIONS: Myocardial CA activation is significantly elevated in human diabetic ischemic cardiomyopathy. These data may open new avenues for targeted treatment of diabetic heart failure

Two- and three-input TALE-based AND logic computation in embryonic stem cells

Biological computing circuits can enhance our ability to control cellular functions and have potential applications in tissue engineering and medical treatments. Transcriptional activator-like effectors (TALEs) represent attractive components of synthetic gene regulatory circuits, as they can be designed de novo to target a given DNA sequence. We here demonstrate that TALEs can perform Boolean logic computation in mammalian cells. Using a split-intein protein-splicing strategy, we show that a functional TALE can be reconstituted from two inactive parts, thus generating two-input AND logic computation. We further demonstrate three-piece intein splicing in mammalian cells and use it to perform three-input AND computation. Using methods for random as well as targeted insertion of these relatively large genetic circuits, we show that TALE-based logic circuits are functional when integrated into the genome of mouse embryonic stem cells. Comparing construct variants in the same genomic context, we modulated the strength of the TALE-responsive promoter to improve the output of these circuits. Our work establishes split TALEs as a tool for building logic computation with the potential of controlling expression of endogenous genes or transgenes in response to a combination of cellular signals

Rapid construction of insulated genetic circuits via synthetic sequence-guided isothermal assembly

In vitro recombination methods have enabled one-step construction of large DNA sequences from multiple parts. Although synthetic biological circuits can in principle be assembled in the same fashion, they typically contain repeated sequence elements such as standard promoters and terminators that interfere with homologous recombination. Here we use a computational approach to design synthetic, biologically inactive unique nucleotide sequences (UNSes) that facilitate accurate ordered assembly. Importantly, our designed UNSes make it possible to assemble parts with repeated terminator and insulator sequences, and thereby create insulated functional genetic circuits in bacteria and mammalian cells. Using UNS-guided assembly to construct repeating promoter-gene-terminator parts, we systematically varied gene expression to optimize production of a deoxychromoviridans biosynthetic pathway in Escherichia coli. We then used this system to construct complex eukaryotic AND-logic gates for genomic integration into embryonic stem cells. Construction was performed by using a standardized series of UNS-bearing BioBrick-compatible vectors, which enable modular assembly and facilitate reuse of individual parts. UNS-guided isothermal assembly is broadly applicable to the construction and optimization of genetic circuits and particularly those requiring tight insulation, such as complex biosynthetic pathways, sensors, counters and logic gates

Brexit and the work-family conflict:a Scottish perspective

This paper examines the Scottish Government’s desire to maintain ties with EU law post-Brexit in the context of employment and equality law, particularly those laws which impact on work-family conflict. The paper critically examines whether there is, or could be, a distinctly Scottish perspective in the context of work-family rights post-Brexit. The paper frames the analysis by considering the potentially gendered implications of Brexit in this context. In doing so, it examines this issue from the perspective of traditional heterosexual dual-partnered working family models. It is argued that rights for working fathers will be most vulnerable post-Brexit, with related consequences for working mothers. Consequently, the implications of Brexit in this context are primarily viewed through the lens of working fathers. The paper then critically examines the Scottish Government’s position on EU employment and equality law in the post-Brexit context

Ultrastructural changes in enterocytes in subjects with Hashimoto's thyroiditis

We have recently described1 mucosal ultrastructural impairments, such as height and thickness of microvilli, space between microvilli, and thickness of tight junctions, in non-coeliac type 1 diabetic patients after a preliminary report of an alteration in intestinal mucosal permeability (IP) evaluated by the lactulose/mannitol (LA/MA) test.2,3 Therefore, in the “aetiological” classification of autoimmunity based on initiating factors,4 the category of diet induced diseases could be expanded to include type 1 diabetes and, perhaps, other endocrine autoimmune diseases. Thyroiditis is the most frequently associated autoimmune endocrine disease with type 1 diabetes. Moreover, type 1 diabetes and Hashimoto thyroiditis present similar pathogenetic mechanisms of cellular damage, a cell mediated autoimmunity induced by Th1 cytokines. However, mucosal intestinal morphology and function have not yet been studied in autoimmune thyroiditis patients. Hence we investigated intestinal mucosal ultrastructural morphology and IP in a group of patients with autoimmune thyroiditis. The study was approved by the local ethics committee. Fourteen patients (12 females and 2 males; mean age 33.2 (SD 10.2) years) and 23 controls (12 females and 11 males; mean age 27.9 (SD 8.01) years) were enrolled into the study after giving written informed consent. The diagnosis of autoimmune thyroiditis was based on the following criteria: plasma autoantibody TPO positive at high titre and a typical thyroiditis ultrasound pattern. All patients were in euthyroidism (normal FT3, FT4, and TSH plasma levels without hormonal therapy). Mean duration of known disease was 5.2 (2.5) years. All patients were negative for the presence of antigliadin antibodies IgA and IgG, antiendomysium antibodies IgA, as well as antihuman transglutaminase IgA following a gluten rich Mediterranean diet. Type 1 diabetes mellitus was excluded according to the 1997 American Diabetes Association criteria, and none of the participants had a family history of diabetes mellitus. Other intestinal and endocrine diseases were excluded through clinical and, when indicated, laboratory evaluation. Food or other allergies were excluded. None of the subjects reported gastrointestinal signs or symptoms, or was a habitual smoker, abuser of alcohol, or regularly took non-steroidal anti-inflammatory drugs

Type IIIb endoleak and relining : a mathematical model of distraction forces

Purpose: To examine the changes in distraction force following relining of a conventional abdominal aortic stent-graft with a type IIIb endoleak using the Nellix endovascular sealing device compared to a unilateral stent-graft. Methods: Relining is often used to repair type IIIb endoleaks, but the consequences to graft stability are unknown. A mathematical model was constructed based on pressure and volume flow through the stent-grafts, incorporating recognized distraction force equations. Steady flow was presumed at peak systolic pressures to calculate the maximum distraction force, with gravity ignored. Distraction forces for 28- to 36-mm-diameter stent-graft bodies with 16-mm limbs were calculated and compared to forces following relining with single and double Nellix devices or the Renu unilateral device. Results: Distraction forces for the 28-, 32-, and 36-mm stent-grafts prior to relining were 5.99, 10.21, and 14.99 N, respectively. Similar forces were reported after relining with bilateral Nellix devices (5.86, 10.08, and 14.86 N, respectively). However, use of a unilateral Nellix increased the distraction forces to 9.92, 14.14, and 18.92 N, respectively. These were comparable to the increase observed after relining with a Renu unilateral stent-graft (9.87, 14.09, and 18.86 N, respectively). The proportional increase in distraction force for a unilateral relining ranged from 26% to 66%, with the greatest increase noted in the smaller diameter main bodies. Conclusion: Relining a stent-graft with a type IIIb endoleak using bilateral Nellix devices does not increase the distraction force. However, a unilateral Nellix device or the Renu system could theoretically increase the distraction force by up to 66%, potentially risking migration and type Ia endoleak. In clinical practice, these results suggest that a relining with bilateral Nellix may have benefits over the Renu unilateral stent-graft
